> Einstein famously didn't have adequate math for special relativity and sought help. General relativity. Special Relativity is an extremely subtle insight into relatively simple mathematics, general relativity is basically a chasm of rich detail that requires advanced mathematics to express and use. Beyond examining the mathematics for yourself, you can see evidence for this in that there are very little texts considering "mathematical" (i.e. for mathematicians) on special relativity but many on general relativity. (For what it's worth, I find some of these mathematics-first one's to be remarkably poor pedagogically and far enough away from any useful physics that I sometimes question why some of them exist, although I am a very long way from being a mathematician).
